v6.1771.18
The F-Gas Containment and Scope 1 Register now says the regulation sets its own GWP basis. The Safeguard Mechanism Position Checker now says the ERC decline factor is written into the Rules. The IT asset and e-waste calculator now calls CPE operational power a fixed default. Only the wording changes; no result, band or factor changes. Why: these sentences live in the tool and calculator code, so the 5 Nov page cleanup did not reach them.
v6.1771.17
The cited memo tutorial now says "key sentence" in place of "load-bearing sentence". Only that wording changes. The tutorial's steps, code and example memo stay the same. Why: the weekly content lint found this one build-room term after the 5 Nov wording cleanup.
v6.1771.16
Two result chips on the semiconductor etch gases calculator fell short of the 4.5:1 contrast target. The Tier 1 confidence chip goes from 4.15:1 to 5.65:1 and the uncertainty chip from 4.48:1 to 5.61:1. Only the text colours change. Why: the presentation check flagged both on the v6.1771.15 deploy.
v6.1771.15
The semiconductor etch gases calculator now shows the total on the other GWP basis under the main result, with the percentage difference, so a reader does not have to re-run it. The copied audit text carries it too. The toggle now reads AR5 and AR6, because "Regulatory" and "Engineering" implied AR6 was not for regulated reporting. AR5 stays the default and no calculated value changes. Why: the choice moves this page's total by about a tenth, so both figures belong in front of the reader.
v6.1771.14
Fixes from the ten-page audit below. • The specialist card on standards and methodology pages opened with "Now it has to hold up all year." where no number was on the page for "it" to mean. Those pages now get a question that stands alone. Calculators, which do have a number, keep the old wording. • Every page carried the id "colophon" twice, because Astra's empty footer printed alongside ours. The empty one is gone. • The car footprint guide's related block came from site-wide recency and was off-topic. It now shows the EV lifecycle calculator and method, and the Tesla and transport guides. • /update-schedule/ gains two booked checks: VCMI claims status and new Code versions (every three months, first 5 February 2027), and the 2027 California Climate Credit months (29 January 2027). • Hero and pin images for the VCMI page corrected: tiers now read Silver 10–50% and Gold 50–100%, and both show the claims as retired. Why: each of these reached readers because nothing checked it. PHP parity: Functions 1705 → 1706 (+gc_related_reference_guide_urls). Hooks unchanged.
v6.1771.13
The Montana page's NorthWestern supply rate check now repeats every quarter, not every six months. NorthWestern changes this rate four times a year, so a half-yearly check could leave the 750 kWh bill out of date for months. The first check stays on 8 January 2027, a week after the next change. Nothing else in the schedule changes, and no page content changes in this release. Why: the booked check should run as often as the rate it watches.
v6.1771.12
The update schedule now books each quarterly NorthWestern supply rate change for the Montana page, starting with 1 January 2027. The earlier booking looked only at the July change, which would have missed an October-style cut. The Flathead Electric check moves to a yearly review each June, and the LIEAP check to each October, because the page now holds current figures for both. The power-cost review stays booked for 15 December 2026. Why: the October supply cut showed that a yearly check would leave NorthWestern's bill out of date for months.
v6.1771.11
The update schedule now books the Montana electricity page's dated facts: the vote on the NorthWestern and Black Hills merger, MDU's final rate order, Flathead Electric's current rates, the 2026 to 2027 LIEAP limits, the review of NorthWestern's power costs, the large-load and Colstrip questions, and the yearly co-op and July rate changes. Montana utilities now show their everyday names in the utility list and calculator. Why: the monthly prices update by themselves, but these decisions fall due on known dates.
v6.1771.10
The update schedule now books the New Hampshire electricity page's dated facts: the Eversource appeal at the state Supreme Court, Liberty's temporary and permanent rate decisions, and the February and August 2027 default supply prices. NHEC and Unitil now show their everyday names in the utility list and calculator. Why: the monthly prices update by themselves, but these decisions fall due on known dates.
v6.1771.9
The update schedule now books the Maine electricity page's dated facts: the low-income supplier bill, the 2027 Standard Offer, the future of CMP's Electric Technology rate, the January and July 2027 rate tables, and the decision on CMP's $189 million rate request. Central Maine Power and Eastern Maine Electric Cooperative now show their everyday names. Why: the monthly prices update by themselves, but these decisions fall due on known dates.
v6.1771.8
The booked check on the West Virginia commission's orders now records that its 31 March release has been read, and that the financing order and the two rate orders have not. The check stays booked for 20 November 2026, the same date as before, and the other six West Virginia checks do not change in this release. Why: the booked check should say exactly what is still unread.
v6.1771.7
The update schedule now books the West Virginia electricity page's dated facts: a direct read of the 2026 PSC orders, the state Supreme Court appeal of the Appalachian Power order, the consumer rate relief bonds, the Mon Power and Potomac Edison ENEC for 2027, the Mitchell cooling tower, the June 2027 step, and the next Appalachian Power ENEC update. Appalachian Power and Wheeling Power now show their everyday names. Why: the monthly prices update by themselves, but these decisions fall due on known dates.
v6.1771.6
The booked check for the Avista and Idaho Falls rate sheets on the Idaho electricity page moves from booked to done, leaving five Idaho checks booked. Idaho Falls Power's fee schedule lists no power cost figure for homes, so the page says that and the January 2025 and October 2026 rates are shown as published. Why: both rate sheets are now on the page.
v6.1771.5
The update schedule now books the Idaho electricity page's dated facts: the Avista and Idaho Falls rate sheets missing from its bill table, Kootenai Electric's 2027 rates, IDACORP's next call, any Idaho Power rate case notice, the June 2027 power cost and Rocky Mountain Power changes, and the end of Avista's stay-out. Idaho Falls Power and Fall River Electric now show their everyday names. Why: the monthly prices update by themselves, but these decisions fall due on known dates.
v6.1771.4
The update schedule now books the Nebraska electricity page's dated facts: NPPD's 2027 rate vote, the Lincoln City Council vote on LES's 2027 rates, OPPD's 2027 plan, the 2027 tariffs behind the worked bills, OPPD's Integrated System Plan, and its time-of-use pilot. Utility names for Nebraska now show their everyday brands (OPPD, LES, NPPD and others). Why: the monthly prices update by themselves, but these decisions fall due within weeks of publishing.
v6.1771.3
The update schedule now books the hand-checked facts on the state electricity pages: dated checks for pending rate cases and tariffs in New Mexico, Utah, Kansas, Arkansas, Oklahoma, Missouri, Nevada, South Carolina, Indiana, Virginia and Illinois, and a six-monthly re-read of the written facts on every state page. Why: the monthly prices update by themselves, but rate cases, tariffs and freezes in the text do not, and those re-checks were not on the public schedule.
v6.1771.2
The electricity rate pages now have their own "US Electricity Prices" section on /data/, directly after Electricity & Grid, with the all-state page first. Its heading links to the Home energy costs topic, which now links to the all-state page from "Your state's prices and climate". EIA and NOAA now show in capitals on /data/. Why: the pages were in the "More datasets" catch-all, and no topic linked to them.
v6.1771.1
Fixed: scrolling could stick at the search and filter bar on the directory pages. The bar flipped between its pinned and full sizes as it reached the top of the screen, and in Safari the page was pushed back up each time, so it could not be scrolled past. The bar now pins once, and nothing below it moves. Why: the marker that detects pinning was also absorbing the height the bar lost, so it moved back into view and cancelled the pin. A fixed marker above the bar now detects pinning and a separate spacer below it takes up the height. Scroll anchoring is off for both height-changing elements.
Editorial
Wording only. No factor, result or method changes on any page. • "Hardcoded" is replaced with plain wording that says what happens: a fixed value, a built-in fallback, or a figure taken from a dated source. • "Citation-grade" and "load-bearing" are replaced with plain wording. "Load-bearing" stays where it means real structure. • Internal notes that had reached readers are removed, such as references to a writing-project reference set, change summaries, editorial section numbers and items flagged to engineering. Where one of these notes said a value was not held in our data, the page still says so in plain words. • Notes about live-reference shortcodes now say that the figures do not update automatically. • One unfinished note on /methodology/ about freezing a worked example is rewritten to say what the page does. • Annex VI of the EU F-Gas Regulation is now described as setting AR4 values, not hardcoding them.

/calculators/scope-1-semiconductor-etch-gases-calculator/ v1.6 → v1.6.1. The page said AR5 matches the GHG Protocol and most current disclosure regimes. That was not supported. IFRS S2 and ESRS ask for the latest IPCC values, which are AR6, and the GHG Protocol's August 2024 GWP table recommends AR6. The US EPA Greenhouse Gas Reporting Program and Australia's NGER Scheme use AR5. All six mentions are corrected. No result changes. Affects: /calculators/scope-1-semiconductor-etch-gases-calculator/

Found by a new check that reads all 1,366 sitemap pages for sums that do not match their inputs and for promises of pages to come. • /methodology/cold-chain-logistics-methodology/ v2.1 → v2.2: the worked example's leakage term corrected from 3.53 t to 4.26 t in two places. 0.9 kg × 4,728 = 4.26 t, and the page's 54.96 t total and 7.7% share already used 4.26 t, so neither changes. • EV vs Petrol & Diesel Lifecycle Carbon Calculator and /calculators/gri-305-emissions-calculator/: notes saying the methodology page was not yet available now link to the live pages. The EV note had also exposed an internal build remark. • /calculators/scope-1-coal-mine-methane-calculator/: now links the F-gas inventory aggregator instead of promising future calculators. • /calculators/flag-emissions-calculator/, SBTi Near-Term Target Calculator | ACA Method & 1.5°C Path and /calculators/scope-3-cat-3-well-to-tank-calculator/: "coming soon" items removed, because those pages do not exist and have no date. • PCAF Financed Emissions Calculators: Loans & Investments and Website & Digital Content Carbon Calculators: promises of unpublished hubs removed. The links to the working hubs stay. • /library/: the Guides card no longer says "Coming soon". The guides are live. • Duplicate page ids removed on calculator FAQ sections. Markup only.

Editorial
Ten pages sampled across post types, then every fact re-read against its primary source. • VCMI Claims Code of Practice: VCMI stopped issuing Carbon Integrity Claims on 23 September 2026 and retired the verification and reporting behind them. Claims Code v3.2 keeps the Code as best-practice guidance, and the page now says so at the top, in the Quick Answer, status banner, version table and FAQ. Tiers corrected to Silver 10% to under 50% and Gold 50% to under 100% (were 20–60 and 60–100). Those figures appeared on the page as the operative ones and it called the correct figures an error; the primary PDFs from v2 (November 2023) to v3.2 all say 10, 50 and 100. Worked example: 100,000 → 50,000 t and 300,000 → 250,000 t. The credit-quality row now states the requirement in the Code: CCP-labelled or Article 6.4 credits, with interim options until 1 January 2027. • Employee Commuting and Homeworking Emissions v1.3 → v1.4: Example D total 1,232.15 → 1,222.27 kg CO2e (969.60 + 252.67). Well-to-tank fuel for commuting is no longer placed in Category 3, which covers only fuel the reporting company itself buys and consumes. • California Electricity Rates per kWh: PG&E, Edison, SDG&E and the Climate Credit v1.0 → v1.1: Climate Credit timing corrected to August and September from 2026 for PG&E, SCE and SDG&E residential customers (was April and October). The 29.75¢ August 2026 price is flagged as held down by the credit. • /calculators/scope-1-semiconductor-etch-gases-calculator/ v1.5 → v1.6: AR6 uplift 10.6% → 9.8%, 1.29 → 1.28 Mt CO2e, because the prose used SF6 at 25,200 while the table uses 24,300. Removed four false comparisons, including that ten tonnes of SF6 outweighs forty-five tonnes of CF4 (235,000 against 298,350 t CO2e). IPCC Tier 2 defaults are now acknowledged. A duplicate page id is removed. • Notes promising a page "when it publishes" are replaced with links to the pages, which already exist, on seven calculators and Industrial Process Emissions: GHG inventory aggregator, iron and steel, aluminium, chemicals, glass and ceramics, coal mine methane and F-gas aggregator. • /methodology/carbon-offset-pricing-methodology/ and What Are Carbon Credits? How They Work and What They Cost: VCMI wording updated for the retirement. • What is the carbon footprint of a car?: ICCT 2025 paper now credited to Negri and Bieker, with its full title. Three factor page intros corrected for capitalisation, and the hotel factors description rewritten.

Editorial
Montana Electricity Rates per kWh: NorthWestern vs the Co-ops v1.0 → v1.1. The page, published earlier the same day, gave about $131 as today's NorthWestern bill, from a June report. NorthWestern's own bill rates page says the supply rate fell on 1 October 2026, taking $8.57, or 6.58%, off a 750 kWh bill. That implies about $122, or about 16.2¢ per kWh, by our arithmetic. • The section heading, Quick Answer, timeline and two answers now carry the October change, and the supply rate section explains the quarterly adjustment. • Added NorthWestern's January 2026 comparison ($118 against a national $144 at 750 kWh) and its rate review figure of $5.89, or 5.35%, against July 2024, beside the 12% reported in January. • Flathead Electric's 2021 figures are replaced by schedule RES01, effective 1 June 2026: $26.66, from 5.47¢ per kWh and $4.93 per kW. Flathead now appears in both rate tables. • LIEAP limits are now the 2026 to 2027 figures from the state: $36,120 for one person and $69,463 for four. • The seasons section said rate changes alone took the price from 12.8¢ to 15.0¢. It now says they explain part of that. Why: NorthWestern's site and Flathead's site did not open from our first connection, so the page leaned on news reports. The audit reached both and found the bill figure out of date. Same-day housekeeping, no figures changed: clearer headings on the West Virginia (v1.2), New Mexico (v1.1) and Idaho (v1.2) electricity pages, whose section headings read too much like other state pages, and a dead source link on the Maine page (v1.1) replaced with Versant Power's eco rates page. Pages published on 5 November with a review date of 3 November now show 5 November.

West Virginia Electricity Rates per kWh: Appalachian Power vs Mon Power v1.0 → v1.1. The page, published earlier the same day, headlined the bond plan at $2.6 billion, which is the figure from Appalachian Power's filing. The Public Service Commission's own release of 31 March 2026, which we could not open before publishing, says the amounts could run to $2.5 billion. • The section heading and the 2027 rates answer now say about $2.5 billion. • The table stays as the company's split of its $2.6 billion filing, labelled as such, because the release gives no split of its own. • Added from the release: Case 25-0310-E-PC, the 27-page order, the separate bill charge, the cut to base and other cost recovery rates at financing, the $16.3 million setup estimate, and the commission's final check before the deal closes. • The financing order itself and the two rate orders are still unread, because the commission's case pages refused our connection. That check stays booked for 20 November 2026. Why: a regulator's figure should lead over a company's filing figure, and the page should say which one it is using.

Idaho Electricity Rates per kWh: What Snowpack Does to Your Bill v1.0 → v1.1. The page, published earlier the same day, gave $123.83 as Avista's bill at 939 kWh from 1 October 2026. That figure is wrong as a bill. It comes from Idaho PUC Order 37187 and shows only the power cost change on the rates in force before 1 September. • Avista's bill at 939 kWh from 1 October 2026 is about $132.50, worked out from Avista's own schedule summary. It reconciles step by step: $119.52 before September, plus $4.31 power cost change, plus $3.45 fixed cost and exchange credit changes, plus $5.22 September base rate step. • The 2026 changes table now shows Avista's 1 October change as power and fixed costs, 6.5%, not power costs, 3.6%. The text now says the power cost change adds $4.31 a month at 939 kWh. • The 1,000 kWh table now includes Avista ($140.32) and Idaho Falls Power ($103.00), with a note on what each row includes. • Sources: added Avista's schedule summary and Schedule 1, and the City of Idaho Falls fee schedules of January 2025 and October 2026. Why: the first version read one order's before-and-after figures as the full bill, and left out two of the state's utilities.
